Within two years of its incorporation the company achieved its goal of reducing its energy usage by five per cent, thus resulting in savings of $40,090 in that time. In terms of water usage, 2000 kL was saved and consequent monetary savings of $1,090 was also seen. Manual handling was no longer needed because all system parameters were controlled automatically including response to stress conditions.

Furthermore, in the two years since the incorporation of the technology, the requirement for chiller descaling has not risen. The cleaning frequency desired has also been achieved. Even though no scaling or fouling issue has been observed in the heat exchanger of the machine, the cleaning schedule of every three months has been maintained to comply with preventive maintenance measures and best practices of the customer. Subsequently, production schedules have not been disrupted in the batch processes and additional labor associated with cleaning has been evaded.
